Tools
Inspect HTTP response headers
Inspect the headers that shape caching, redirects, proxy behavior, and security posture.
How it works
See what a URL returns before parsing the body
Headers reveal redirects, cache rules, content type, and security controls.
Step 1
Enter a URL
Paste the page or API endpoint you want to inspect.
Step 2
We send a HEAD request
The checker requests headers with a short timeout and follows the server response.
Step 3
You scan the headers
Review status, redirects, cache hints, cookies, and security directives.
Debug redirects
Confirm status lines and Location headers quickly.
Cache review
Inspect cache-control, expires, etag, and related behavior.
Security visibility
Spot common protection headers without opening devtools.
